Which proposition is abbreviated as O?

Explanation:
In traditional categorical logic, propositions are classified by quantity (universal vs. particular) and quality (affirmative vs. negative). The form abbreviated as O is the particular negative: Some S are not P. It asserts that at least one member of the subject class S does not belong to the predicate class P. For example, Some students are not passing calculus. This is different from the universal forms (All S are P, No S are P) and the particular affirmative form (Some S are P). So the proposition abbreviated as O is "Some S are not P."
